Caterpillar 5P-9506 Retaining Ring Assembly Kit

5P-9506 External Retaining Ring from Caterpillar is a groove-retaining component designed to sit in an external groove on a shaft or housing to secure parts in place. It carries a thickness specification of 2.36 mm, aligning with Cat groove standards used in many Caterpillar assemblies. This external retaining ring is used to locate and retain gears, bearings, collars, or spacers within drivetrain, hydraulic, or auxiliary assemblies where a groove-based retention is required. The 2.36 mm thickness provides the strength needed to resist axial movement while preserving the necessary clearances for installation and removal with standard retaining ring pliers. Cataloged as 5P-9506, it represents Caterpillar’s lineup of ring-type retention hardware designed to fit precise groove dimensions used across Cat equipment. When selecting this part, verify the corresponding groove width and diameter in the Caterpillar parts catalog or consult a Cat dealer to confirm compatibility with your specific machine model. Rely on the official Cat parts system to match 5P-9506 to the correct retention groove specification and application context, ensuring reliable component retention in service and during maintenance.
